Turkey

Turkey (Turkish: Türkiye [ˈtyɾcije]), officially Republic of Turkey (Turkish: Türkiye Cumhuriyeti [ˈtyɾcije dʒumˈhuɾijeti], is a transcontinental country located mainly in Western Asia, with a smaller portion on the Balkan Peninsula in Southeast Europe. East Thrace, located in Europe, is separated from Anatolia by the Sea of Marmara, the Bosphorous strait and the Dardanelles (collectively called the Turkish Straits). Turkey is bordered by Greece and Bulgaria to its northwest; Georgia to its northeast; Armenia, the Azerbaijani exclave of Nakhchivan and Iran to the east; and Iraq and Syria to the south. Istanbul is the largest city, but more central Ankara is the capital. Approximately 70 to 80 per cent of the country's citizens identify as Turkish. Kurds are the largest minority; the size of the Kurdish population is a subject of dispute with estimates placing the figure at anywhere from 12 to 25 percent of the population.

At various points in its history, the region has been inhabited by diverse civilizations including the Assyrians, Greeks, Thracians, Phrygians, Urartians, and Armenians. Hellenization started during the era of Alexander the Great and continued into the Byzantine era. The Seljuk Turks began migrating into the area in the 11th century, and their victory over the Byzantines at the Battle of Manzikert in 1071 symbolizes the start and foundation of Turkey.The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243, when it disintegrated into small Turkish principalities. Beginning in the late 13th-century, the Ottomans started uniting these Turkish principalities. After Mehmed II conquered Constantinople in 1453, Ottoman expansion continued under Selim I. During the reign of Suleiman the Magnificent the Ottoman Empire encompassed much of Southeast Europe, West Asia and North Africa and became a world power. In the following centuries the state entered a period of decline with a gradual loss of territories and wars. In an effort to consolidate the weakening social and political foundations of the empire, Mahmut II started a period of modernisation in the early 19th century, bringing reforms in all areas of the state including the military and bureaucracy along with the emancipation of all citizens.

In 1913, a coup d'état effectively put the country under the control of the Three Pashas. During World War I, the Ottoman government committed genocides against its Armenian, Assyrian and Pontic Greek subjects.Following the war, the conglomeration of territories and peoples that formerly comprised the Ottoman Empire was partitioned into several new states.The Turkish War of Independence, initiated by Mustafa Kemal Atatürk and his colleagues against occupying Allied Powers, resulted in the abolition of monarchy in 1922 and the establishment of the Republic of Turkey in 1923, with Atatürk as its first president.[24] Atatürk enacted numerous reforms, many of which incorporated various aspects of Western thought, philosophy, and customs into the new form of Turkish government.The Kurdish–Turkish conflict, an armed conflict between the Republic of Turkey and Kurdish insurgents, has been active since 1984 primarily in the southeast of the country. Various Kurdish groups demand separation from Turkey to create an independent Kurdistan or to have autonomy and greater political and cultural rights for Kurds in Turkey.

Turkey is a charter member of the UN, an early member of NATO, the IMF and the World Bank, and a founding member of the OECD, OSCE, BSEC, OIC and G-20. After becoming one of the first members of the Council of Europe in 1949, Turkey became an associate member of the EEC in 1963, joined the EU Customs Union in 1995 and started accession negotiations with the European Union in 2005 which have been effectively stopped by the EU in 2017 due to "Turkey's path toward autocratic rule".Turkey's economy and diplomatic initiatives led to its recognition as a regional power while its location has given it geopolitical and strategic importance throughout history. Turkey is a secular, unitary, formerly parliamentary republic which adopted a presidential system with a referendum in 2017; the new system came into effect with the presidential election in 2018. Turkey's current administration headed by president Recep Tayyip Erdoğan of the AKP has enacted measures to increase the influence of Islam, and undermine Kemalist policies and freedom of the press.

History
The Anatolian peninsula, comprising most of modern Turkey, is one of the oldest permanently settled regions in the world. Various ancient Anatolian populations have lived in Anatolia, from at least the Neolithic period until the Hellenistic period. Many of these peoples spoke the Anatolian languages, a branch of the larger Indo-European language family.In fact, given the antiquity of the Indo-European Hittite and Luwian languages, some scholars have proposed Anatolia as the hypothetical centre from which the Indo-European languages radiated.The European part of Turkey, called Eastern Thrace, has also been inhabited since at least forty thousand years ago, and is known to have been in the Neolithic era by about 6000 BC.

Göbekli Tepe is the site of the oldest known man-made religious structure, a temple dating to circa 10,000 BC while Çatalhöyük is a very large Neolithic and Chalcolithic settlement in southern Anatolia, which existed from approximately 7500 BC to 5700 BC. It is the largest and best-preserved Neolithic site found to date and in July 2012 was inscribed as a UNESCO World Heritage Site.The settlement of Troy started in the Neolithic Age and continued into the Iron Age.

The earliest recorded inhabitants of Anatolia were the Hattians and Hurrians, non-Indo-European peoples who inhabited central and eastern Anatolia, respectively, as early as c. 2300 BC. Indo-European Hittites came to Anatolia and gradually absorbed the Hattians and Hurrians c. 2000–1700 BC. The first major empire in the area was founded by the Hittites, from the 18th through the 13th century BC. The Assyrians conquered and settled parts of southeastern Turkey as early as 1950 BC until the year 612 BC,although they remained a minority in the region, namely in Hakkari, up until the early 20th century AD.

Pre-emerged in Assyrian inscriptions in the 9th century BC as a powerful northern rival of Assyria.Following the collapse of the Hittite empire c. 1180 BC, the Phrygians, an Indo-European people, achieved ascendancy in Anatolia until their kingdom was destroyed by the Cimmerians in the 7th century BC. Starting from 714 BC, Urartu shared the same fate and dissolved in 590 BC,when it was conquered by the Medes. The most powerful of Phrygia's successor states were Lydia, Caria and Lycia.

Antiquity
Starting around 1200 BC, the coast of Anatolia was heavily settled by Aeolian and Ionian Greeks. Numerous important cities were founded by these colonists, such as Miletus, Ephesus, Smyrna (now İzmir) and Byzantium (now Istanbul), the latter founded by Greek colonists from Megara in 657 BC. The first state that was called Armenia by neighbouring peoples was the state of the Armenian Orontid dynasty, which included parts of eastern Turkey beginning in the 6th century BC. In Northwest Turkey, the most significant tribal group in Thrace was the Odyrisians, founded by Teres I.

All of modern-day Turkey was conquered by the Persian Achaemenid Empire during the 6th century BC.The Greco-Persian Wars started when the Greek city states on the coast of Anatolia rebelled against Persian rule in 499 BC. The territory of Turkey later fell to Alexander the Great in 334 BC,which led to increasing cultural homogeneity and Hellenization in the area.

Following Alexander's death in 323 BC, Anatolia was subsequently divided into a number of small Hellenistic kingdoms, all of which became part of the Roman Republic by the mid-1st century BC.The process of Hellenization that began with Alexander's conquest accelerated under Roman rule, and by the early centuries of the Christian Era, the local Anatolian languages and cultures had become extinct, being largely replaced by ancient Greek language and culture. From the 1st century BC up to the 3rd century CE, large parts of modern-day Turkey were contested between the Romans and neighbouring Parthians through the frequent Roman-Parthian Wars.

Seljuks and the Ottoman Empire
The House of Seljuk was a branch of the Kınık Oğuz Turks who resided on the periphery of the Muslim world, in the Yabgu Khaganate of the Oğuz confederacy, to the north of the Caspian and Aral Seas, in the 9th century.In the 10th century, the Seljuks started migrating from their ancestral homeland into Persia, which became the administrative core of the Great Seljuk Empire, after its foundation by Tughril.

In the latter half of the 11th century, the Seljuk Turks began penetrating into medieval Armenia and the eastern regions of Anatolia. In 1071, the Seljuks defeated the Byzantines at the Battle of Manzikert, starting the Turkification process in the area; the Turkish language and Islam were introduced to Armenia and Anatolia, gradually spreading throughout the region. The slow transition from a predominantly Christian and Greek-speaking Anatolia to a predominantly Muslim and Turkish-speaking one was underway. The Mevlevi Order of dervishes, which was established in Konya during the 13th century by Sufi poet Celaleddin Rumi, played a significant role in the islamization of the diverse people of Anatolia who had previously been Hellenized. Thus, alongside the Turkification of the territory, the culturally Persianized Seljuks set the basis for a Turko-Persian principal culture in Anatolia,which their eventual successors, the Ottomans, would take over.

In 1243, the Seljuk armies were defeated by the Mongols at the Battle of Köse Dağ, causing the Seljuk Empire's power to slowly disintegrate. In its wake, one of the Turkish principalities governed by Osman I would evolve over the next 200 years into the Ottoman Empire. In 1453, the Ottomans completed their conquest of the Byzantine Empire by capturing its capital, Constantinople.

Topkapı and Dolmabahçe palaces were the primary residences of the Ottoman Sultans and the administrative centre of the empire between 1465 to 1856 and 1856 to 1922,respectively.In 1514, Sultan Selim I (1512–1520) successfully expanded the empire's southern and eastern borders by defeating Shah Ismail I of the Safavid dynasty in the Battle of Chaldiran. In 1517, Selim I expanded Ottoman rule into Algeria and Egypt, and created a naval presence in the Red Sea. Subsequently, a contest started between the Ottoman and Portuguese empires to become the dominant sea power in the Indian Ocean, with a number of naval battles in the Red Sea, the Arabian Sea and the Persian Gulf. The Portuguese presence in the Indian Ocean was perceived as a threat to the Ottoman monopoly over the ancient trade routes between East Asia and Western Europe. Despite the increasingly prominent European presence, the Ottoman Empire's trade with the east continued to flourish until the second half of the 18th century.

The Ottoman Empire's power and prestige peaked in the 16th and 17th centuries, particularly during the reign of Suleiman the Magnificent, who personally instituted major legislative changes relating to society, education, taxation and criminal law. The empire was often at odds with the Holy Roman Empire in its steady advance towards Central Europe through the Balkans and the southern part of the Polish-Lithuanian Commonwealth. At sea, the Ottoman Navy contended with several Holy Leagues, such as those in 1538, 1571, 1684 and 1717 (composed primarily of Habsburg Spain, the Republic of Genoa, the Republic of Venice, the Knights of St. John, the Papal States, the Grand Duchy of Tuscany and the Duchy of Savoy), for the control of the Mediterranean Sea. In the east, the Ottomans were often at war with Safavid Persia over conflicts stemming from territorial disputes or religious differences between the 16th and 18th centuries.The Ottoman wars with Persia continued as the Zand, Afsharid, and Qajar dynasties succeeded the Safavids in Iran, until the first half of the 19th century. Even further east, there was an extension of the Habsburg-Ottoman conflict, in that the Ottomans also had to send soldiers to their farthest and easternmost vassal and territory, the Sultanate of Aceh in Southeast Asia, to defend it from European colonizers as well as the Latino invaders that had crossed from Latin-America and had Christianized formerly Muslim-dominated Philippines.From the 16th to the early 20th centuries, the Ottoman Empire also fought many wars with the Russian Tsardom and Empire. These were initially about Ottoman territorial expansion and consolidation in southeastern and eastern Europe; but starting from the latter half of the 18th century, they became more about the survival of the Ottoman Empire, which had begun to lose its strategic territories on the northern Black Sea coast to the advancing Russians.

Ottomans joined World War I on the side of the Central Powers.From the second half of the 18th century onwards, the Ottoman Empire began to decline. The Tanzimat reforms of the 19th century, which had been instituted by Mahmud II, were aimed to modernise the Ottoman state in line with the progress that had been made in Western Europe. The efforts of Midhat Pasha during the late Tanzimat era led the Ottoman constitutional movement of 1876, which introduced the First Constitutional Era, but these efforts proved to be inadequate in most fields, and failed to stop the dissolution of the empire.As the empire gradually shrank in size, military power and wealth, especially after the Ottoman economic crisis and default in 1875 which led to uprisings in the Balkan provinces that culminated into the Russo-Turkish War of 1877–78, many Balkan Muslims migrated to the Empire's heartland in Anatolia,along with the Circassians fleeing the Russian conquest of the Caucasus. The decline of the Ottoman Empire led to a rise in nationalist sentiment among its various subject peoples, leading to increased ethnic tensions which occasionally burst into violence, such as the Hamidian massacres of Armenians.

During the "First Constitutional Era", the constitution and parliament had been suspended by Sultan Abdul Hamid II. Thirty years later, “the Young Turk Revolution of 1908“ restored the Ottoman constitution and parliament, but the 1913 Ottoman coup d'état effectively put the country under the control of the Three Pashas, making sultans Mehmed V and Mehmed VI largely symbolic figureheads with no real political power.

The Ottoman Empire entered World War I on the side of the Central Powers and was ultimately defeated. During the war, the empire's Armenians were deported to Syria as part of the Armenian Genocide. As a result, an estimated 800,000 to 1,500,000 Armenians were killed. The Turkish government has refused to acknowledge the events as genocide and claims that Armenians were only relocated from the eastern war zone.Genocidal campaigns were also committed against the empire's other minority groups such as the Assyrians and Greeks. Following the Armistice of Mudros on 30 October 1918, the victorious Allied Powers sought to partition the Ottoman state through the 1920 Treaty of Sèvres.

Republic of Turkey
The occupation of Istanbul (1918) and Izmir (1919) by the Allies in the aftermath of World War I prompted the establishment of the Turkish National Movement. Under the leadership of Mustafa Kemal Pasha, a military commander who had distinguished himself during the Battle of Gallipoli, the Turkish War of Independence (1919–1923) was waged with the aim of revoking the terms of the Treaty of Sèvres.

By 18 September 1922 the Greek, Armenian and French armies were expelled,and the Ankara-based Turkish regime, which had declared itself the legitimate government of the country on 23 April 1920, started to formalise the legal transition from the old Ottoman into the new Republican political system. On 1 November 1922, the Turkish Parliament in Ankara formally abolished the Sultanate, thus ending 623 years of monarchical Ottoman rule. The Treaty of Lausanne of 24 July 1923 led to the international recognition of the sovereignty of the newly formed ”Republic of Turkey “ as the successor state of the Ottoman Empire, and the republic was officially proclaimed on 29 October 1923 in Ankara, the country's new capital.The Lausanne Convention stipulated a population exchange between Greece and Turkey, whereby 1.1 million Greeks left Turkey for Greece in exchange for 380,000 Muslims transferred from Greece to Turkey.

Eighteen female deputies joined the Turkish Parliament with the 1935 general elections. Turkish women gained the right to vote a decade or more before women in Western European countries like France, Italy, and Belgium, a mark of the far-reaching social changes initiated by Atatürk.Mustafa Kemal became the republic's first President and subsequently introduced Atatürk's Reforms. The reforms aimed to transform the old religion-based and multi-communal Ottoman constitutional monarchy into an essentially Turkish nation state that would be governed as a parliamentary republic) under a secular constitution.With the Surname Law of 1934, the Turkish Parliament bestowed upon Mustafa Kemal the honorific surname "Atatürk" (Father of the Turks)

İsmet İnönü became Turkey's second President following Atatürk's death on 10 November 1938. In 1939 Turkey annexed the Republic of Hatay. Turkey remained neutral during most of World War II, but entered the closing stages of the war on the side of the Allies on 23 February 1945. On 26 June 1945, Turkey became a charter member of the United Nations. In the following year, the single-party period in Turkey came to an end, with the first multiparty elections in 1946. In 1949 Turkey became a member of the Council of Europe.

The Democratic Party established by Celâl Bayar won the 1950, 1954 and 1957 general elections and stayed in power for a decade, with Adnan Menderes as the Prime Minister and Bayar as the President. After participating with the United Nations forces in the Korean War, Turkey joined NATO in 1952, becoming a bulwark against Soviet expansion into the Mediterranean. Turkey subsequently became a founding member of the OECD in 1961, and an associate member of the EEC in 1963.

The country's tumultuous transition to multiparty democracy was interrupted by military coups d'état in 1960, 1971, and 1980, as well as a military memorandum in 1997. Between 1960 and the end of the 20th century, the prominent leaders in Turkish politics who achieved multiple election victories were Süleyman Demirel, Bülent Ecevit and Turgut Özal.

Following a decade of Cypriot intercommunal violence and the coup in Cyprus on 15 July 1974 staged by the EOKA B paramilitary organisation, which overthrew President Makarios and installed the pro-Enosis (union with Greece) Nikos Sampson as dictator, Turkey invaded Cyprus on 20 July 1974 by unilaterally exercising Article IV in the Treaty of Guarantee (1960), but without restoring the status quo ante at the end of the military operation. In 1983 the Turkish Republic of Northern Cyprus, which is recognised only by Turkey, was established.The Annan Plan for reunifying the island was supported by the majority of Turkish Cypriots, but rejected by the majority of Greek Cypriots, in separate referendums in 2004. However, negotiations for solving the Cyprus dispute are still ongoing between Turkish Cypriot and Greek Cypriot political leaders.

In 1978, the Kurdistan Workers' Party (considered a terrorist organization by Turkey and its NATO allies) was founded, and since 1984 the PKK and other Kurdish groups are engaged in an armed conflict with Turkey. The Kurds demand separation from Turkey to create an independent Kurdistan or to have autonomy and greater political and cultural rights for Kurds inside the Republic of Turkey. More than 40,000 people have died as a result of the conflict.

Since the liberalisation of the Turkish economy in the 1980s, the country has enjoyed stronger economic growth and greater political stability.Turkey applied for full membership of the EEC in 1987, joined the EU Customs Union in 1995 and started accession negotiations with the European Union in 2005.

In 2013, widespread protests erupted in many Turkish provinces, sparked by a plan to demolish Gezi Park but soon growing into general anti-government dissent.[109] On 15 July 2016, an unsuccessful coup attempt tried to oust the government. As a reaction to the failed coup d'état, the government is currently carrying out mass purges.



Politics
The judiciary is nominally independent from the executive and the legislature, but the constitutional changes that came into effect with the referendums in 2007, 2010 and 2017 gave larger powers to the President and the ruling party for appointing or dismissing judges and prosecutors.The Constitutional Court is charged with ruling on the conformity of laws and decrees with the constitution. The Council of State is the tribunal of last resort for administrative cases, and the High Court of Appeals for all others.

Universal suffrage for both sexes has been applied throughout Turkey since 1933 and before most countries, and every Turkish citizen who has turned 18 years of age has the right to vote. There are 600 members of parliament who are elected for a four-year term by a party-list proportional representation system from 85 electoral districts. The Constitutional Court can strip the public financing of political parties that it deems anti-secular or separatist, or ban their existence altogether.The electoral threshold is 10 percent of the votes.

Supporters of Atatürk's reforms are called Kemalists, as distinguished from Islamists, representing the two diverging views regarding the role of religion in legislation, education and public life. The Kemalist view supports a form of democracy with a secular constitution and Westernised culture, while maintaining the necessity of state intervention in the economy, education and other public services.Since its foundation as a republic in 1923, Turkey has developed a strong tradition of secularism.However, since the 1980s, issues such as income inequality and class distinction have given rise to Islamic populism, a movement that supports a larger role for religion in government policies, and in theory supports obligation to authority, communal solidarity and social justice; though what that entails in practice is often contested.Turkey under Recep Tayyip Erdoğan and the AKP has been described as becoming increasingly authoritarian. Even before the constitutional referendum in 2017 the Council of Europe had noted the country's autocratic tendencies and warned of a "dramatic regression of Turkey's democratic order". Many elements in the constitutional reform package that was approved with the referendum in 2017 have increased concerns in the European Union regarding democracy and the separation of powers in Turkey.

As of 2017 the Economist Intelligence Unit's Democracy Index rates Turkey at 4.88 (on a 0–10 scale), classifying Turkey as a Hybrid Regime. In 2018, Freedom House rated Turkey at 32 (on a 0–100 scale) as Not Free.

Foreign Relations
In line with its traditional Western orientation, relations with Europe have always been a central part of Turkish foreign policy. Turkey became one of the first members of the Council of Europe in 1949, applied for associate membership of the EEC (predecessor of the European Union) in 1959 and became an associate member in 1963. After decades of political negotiations, Turkey applied for full membership of the EEC in 1987, became an associate member of the Western European Union in 1992, joined the EU Customs Union in 1995 and has been in formal accession negotiations with the EU since 2005.Today, EU membership is considered as a state policy and a strategic target by Turkey. Turkey's support for Northern Cyprus in the Cyprus dispute complicates Turkey's relations with the EU and remains a major stumbling block to the country's EU accession bid.

The other defining aspect of Turkey's foreign policy was the country's long-standing strategic alliance with the United States.The Truman Doctrine in 1947 enunciated American intentions to guarantee the security of Turkey and Greece during the Cold War, and resulted in large-scale U.S. military and economic support. In 1948 both countries were included in the Marshall Plan and the OEEC for rebuilding European economies.The common threat posed by the Soviet Union during the Cold War led to Turkey's membership of NATO in 1952, ensuring close bilateral relations with the US. Subsequently, Turkey benefited from the United States' political, economic and diplomatic support, including in key issues such as the country's bid to join the European Union.[204] In the post–Cold War environment, Turkey's geostrategic importance shifted towards its proximity to the Middle East, the Caucasus and the Balkans.

The Turkish Armed Forces collecvirely rank as the second largest standing military force in NATO, after the US Armed Forces. Turkey joined the alliance in 1952.

The independence of the Turkic states of the Soviet Union in 1991, with which Turkey shares a common cultural and linguistic heritage, allowed Turkey to extend its economic and political relations deep into Central Asia,thus enabling the completion of a multi-billion-dollar oil and natural gas pipeline from Baku in Azerbaijan to the port of Ceyhan in Turkey. The Baku–Tbilisi–Ceyhan pipeline forms part of Turkey's foreign policy strategy to become an energy conduit from the Caspian Sea basin to Europe.

However, in 1993, Turkey sealed its land border with Armenia in a gesture of support to Azerbaijan (a Turkic state in the Caucasus region) during the Nagorno-Karabakh War, and it remains closed.Under the AKP government, Turkey's influence has grown in the formerly Ottoman territories of the Middle East and the Balkans, based on the "strategic depth" doctrine (a terminology that was coined by Ahmet Davutoğlu for defining Turkey's increased engagement in regional foreign policy issues), also called Neo-Ottomanism. Following the Arab Spring in December 2010, the choices made by the AKP government for supporting certain political opposition groups in the affected countries have led to tensions with some Arab states, such as Turkey's neighbour Syria since the start of the Syrian civil war, and Egypt after the ousting of President Mohamed Morsi.As of 2016, Turkey doesn't have an ambassador in either Syria or Egypt.[213] Diplomatic relations with Israel were also severed after the Gaza flotilla raidin 2010, but were normalised following a deal in June 2016. These political rifts have left Turkey with few allies in the East Mediterranean, where rich natural gas fields have recently been discovered;in sharp contrast with the original goals that were set by the former Foreign Minister (later Prime Minister) Ahmet Davutoğlu in his "zero problems with neighbours" foreign policy doctrine. In 2015, Turkey, Saudi Arabia and Qatar formed a "strategic alliance" against Syrian President Bashar al-Assad.However, following the rapprochement with Russia in 2016, Turkey revised its stance regarding the solution of the conflict in Syria. In January 2018, the Turkish military and the Turkish-backed forces, including the Free Syrian Army and Ahrar al-Sham,began an intervention in Syria aimed at ousting U.S.-backed YPG from the enclave of AfrinIn June 2018, Turkey and the United States agreed on a plan for the withdrawal of YPG from the northern Syrian city of Manbij and to jointly maintain security and stability there.

Geography
Turkey is a transcontinental Eurasian country.Asian Turkey, which includes 97 percent of the country, is separated from European Turkey by the Bosphorus, the Sea of Marmara, and the Dardanelles. European Turkey comprises 3 percent of the country's territory.The territory of Turkey is more than 1,600 kilometres (990 miles) long and 800 kilometres (500 miles) wide, with a roughly rectangular shape. It lies between latitudes 35° and 43° N, and longitudes 25° and 45° E. Turkey's land area, including lakes, occupies 783,562 square kilometres (302,535 square miles), of which 755,688 square kilometres (291,773 square miles) are in Southwest Asia and 23,764 square kilometres (9,175 square miles) in Europe.Turkey is the world's 37th-largest country in terms of area. The country is encircled by seas on three sides: the Aegean Sea to the west, the Black Sea to the north and the Mediterranean to the south. Turkey also contains the Sea of Marmara in the northwest.

Van is the largest lake in the country and is located in eastern Anatolia.The European section of Turkey, eastern Thrace is located at the easternmost edge the Balkan peninsula). It forms the border between Turkey and its neighbors Greece and Bulgaria. The Asian part of the country is comprised mostly by the peninsula of Anatolia, which consists of a high central plateau with narrow coastal plains, between the Köroğlu and Pontic mountain ranges to the north and the Taurus Mountains to the south. Eastern Turkey has a more mountainous landscape and is home to the sources of rivers such as the Euphrates, Tigris and Aras. The western portion of the Armenian highland is located in eastern Turkey; this region contains Mount Ararat, Turkey's highest point at 5,137 metres (16,854 feet)and Lake Van, the largest lake in the country. Southeastern Turkey is located within the northern plains of Upper Mesopotamia.

Turkey is divided into seven geographical regions: Marmara, Aegean, Black Sea, Central Anatolia, Eastern Anatolia, Southeastern Anatolia and the Mediterranean. The uneven north Anatolian terrain running along the Black Sea resembles a long, narrow belt. This region comprises approximately one-sixth of Turkey's total land area. As a general trend, the inland Anatolian plateau becomes increasingly rugged as it progresses eastward.

Turkey's varied landscapes are the product of complex earth movements that have shaped the region over thousands of years and still manifest themselves in fairly frequent earthquakes and occasional volcanic eruptions. The Bosphorus and the Dardanelles owe their existence to the fault lines running through Turkey that led to the creation of the Black Sea. The North Anatolian Fault Line runs across the north of the country from west to east, along which major earthquakes took place in history. The latest of those big earthquakes was the 1999 İzmit earthquake.
